Two software ‘Goody’ books, each 5.5 x 8.5, used by Gene Kranz throughout the Apollo program from his Flight Director's console. These software manuals contain the codes that represent to key to understanding the computer operating systems for both the Lunar Module (entitled “Luminary 1D”) and Command Module (entitled “Colossus 2E”) for every manned mission, including Apollo 11. They are the actual computer manuals for the computer systems of the lunar module and command module. In order to keep these software books close at hand, Gene attached them to his console by way of two still-intact rings. Accompanied by a letter of authenticity from Kranz that reads in part, “The Apollo CM & LM Goody Books pictured above come from my personal space memorabilia archives. I kept these important reference materials at my console throughout the Apollo program. They were utilized for every manned mission.”
The so-named ‘goody book’ was used by mission control officials to access critical or often-used information more quickly and efficiently. Interestingly, page LM-15 of this goody book shows the infamous 1202 Alarm Code—a program alarm from the guidance computer signaling an ‘executive overflow,’ meaning the computer might not be keeping up with its tasks. As the lunar module passed 35,000 feet above the moon, the capsule’s computer display began to sound a warning, with Buzz Aldrin quickly determining the problem and leading Neil Armstrong to ask mission control, ‘Give us a reading on the 1202 Program Alarm.’ As the mission commander waited to see whether an abort was imminent, engineers on Earth concluded that the warning would have no impact on the landing, and that high-priority computing tasks were still being completed. NASA guidance officer Steve Bales notified Kranz, ‘We’re go on that alarm,’ deciding not to abort the lunar landing and completing the historic journey. An incredibly significant and truly wonderful slice of manned space program history from one of its key players. RRAuction COA.
